Have students either do a complete count of components or use the Quick Kit Inventory Sheets to speed the process of accounting for most of the kit parts.

Parts Walk-Thru

Be sure to use the proper part names as students learn the kit components. Part of engineering is precision in speech, so try to avoid having students refer to parts as "the round thingy", etc. These Part Picture and Names Sheets have the actual names of the components.

Below are some points to emphasize as you walk students through the parts:

Electronics (mostly located in lower tray)

EV3 brick

Ports

Inputs (4) for sensors

Outputs (4) for motors

USB (1) for computer downloads

Buttons

Screen

Battery (rechargeable & cover for AA’s)

Motors (2 large, 1 medium)

Students can manipulate red hub

Insert any axle and attach any wheel to demonstrate motion

Sensors - Students can speculate on functions

Color

notice LED light emitter and detector

Touch

notice axle connection to extend sensor reach

Ultrasonic

notice emitter and receiver

Gyro

notice the symbol on the top

Wires

Students can attach to brick/motors/sensors

USB cable for downloading

Connectors cable for sensors/motors (different lengths)

Structural Components

Beams

Students can compare lengths

Angled Beams

Notice some have axle connections at ends (arms)

Studded Bricks

Colored bricks fit over lights as colored lens (students can attach)

Plates

Studded Plates

1/3 thickness of bricks

Curved Beam plates

½ thickness of beams

Connectors

Pegs

Short and long friction pegs

Axle/pegs; friction and non-friction

Students can test difference by building two “propellers” with friction and non-friction pegs

Joints

Axle and pegs fittings

Students can attach pegs and axles to explore different configurations (or wait until Part Exploration, next)

Peg-Joints

Students can assemble structures using these with beams and axles (or wait until Part Exploration, next)

Specialty Parts

Axles

Students can attach to other elements

Lengths measured in “beam holes”

Structural and Functional uses

Bushings

Student can slide on to any axle

Attach gear to medium length axle and insert in any beam

Students can use bushing on opposite side of beam to keep gear in place
